This article is devoted to thermal oceanicity that characterize differences of change air temperature during the warmest period of the year in various types of climate. The paper studied the regularities of spatial distribution of thermal oceanicity index in Ukraine for the period 1961-1990 years. The data of 187 weather stations was processed that quite uniformly distributed across the country and representing all its climatic zones. The degree of influence of components of the geographical environment was estimated using regression analysis techniques. The simple linear regression met&hod was used for estimation of thermal oceanicity depending on the geographical location of individual components of weather station - its longitude, latitude, altitude and average degree of closeness of the horizon, and the method of multiple linear& regression - on the totality of the conditions geographical location of the weather stations. It was found that weather station geographical coordinates and altitudes reveal a significant impact on the thermal oceanicity across the country. The ther&mal oceanicity in Ukraine usually decrease from west to east with an average speed of 0,22°C per 1°of longitude. The thermal oceanicity decreases from south to north even faster (-0,83°C/1<). The largest absolute values of oceanicity (-1,5°C) occur o&n the Southern coast of Crimea, and the lowest value (-15,0°C) - on the east, where the total impact of Black sea, Azov sea and Atlantic is the lowest. Vertical gradient of thermal oceanicity is about 0,39°C per 100 m of height. The 3-factor regressi&on model was built for the above elements of geographical location. It was determined that the contribution of geographic longitude in the total variance of thermal oceanicity is 38.3%, latitude - 53.1%, altitude - only 8.5%.
